Comparison of Using Modified and Nonmodified Books on Comprehension of Students With Extensive Support Needs

Modified books are frequently used as comprehension supports for students with extensive support needs (ESN), despite limited evaluations of their creation process or impact on comprehension. This study evaluates the impact of individualized book and comprehension question modifications made through a systematic decision-making process on student comprehension during nonfiction shared book reading in general education classes. A repeated acquisition single-case research design was used to compare student comprehension of nonmodified and modified books for one first-grade and one fourth-grade student with autism and moderate intellectual disability. Findings indicate student comprehension was higher after reading modified grade-level, nonfiction books compared with similarly matched nonmodified books. These findings show students with ESN can access grade-level books in general education settings with individualized modifications. Recommendations for research and practice are shared. These recommendations include a systematic process for identification of the type and intensity of book modifications that may support comprehension for students with ESN.
